Angelique, Diego, Emma and Can joined the group. The Zürch Force has assembled!
We are delighted to report that our ultrafast laser system arrived today in no less than 17 boxes. Many thanks to our effortless helpers on campus and the facility colleagues helping to get a temporary storage area prepared quickly. Quite some heavy lifting today, but totally worth it.
We welcome Ruoxu to our group as summer student. Ruoxu is starting her graduate research this Fall at Berkeley. She received her undergraduate degree from Grinnell College.
We are excited to announce that the Zuerch Lab is moving from the Fritz Haber Institute in Berlin, Germany, to the University of California at Berkeley following Michael accepting an offer to join the Faculty at Berkeley in the College of Chemistry as Assistant Professor. Our new labs are under construction in the D-levels of Giauque Hall and the offices in the neighbouring Hildebrand Hall on the Berkeley Campus.
Our paper “Retrieval of the complex-valued refractive index of germanium near the M4,5 absorption edge” has been published in the Journal of the Optical Society of America B. In this work we show that the complex-valued index of refraction of germanium in the extreme ultraviolet (XUV) is measured by multi- angle reflectance of synchrotron radiation. The resulting index of refraction is higher resolution than previously measured values. It reveals new structures attributed to transitions from the 3d-core orbitals to the Σ5c,2 and the X5c,2 conduction bands. Additionally, we show that the problem of total external reflection, which renders multi-angle reflectance measurements insensitive to the complex-valued refractive index at grazing incidence, can be overcome by employing measurements at angles of incidence away from the critical angle.
